Intrinsically safe design for weighing in hazardous areas

When electrical equipment, such as a weighing system, is used in a location classified as hazardous, it has to provide the required level of protection and be certified to operate in the environment. The selection of an appropriate protection method is based on the classification of the hazardous area.

Intrinsic safety is one of the safest protection methods and it is a common design for weighing equipment in certified hazardous areas. The method is different from any other recognised method of ignition protection for certified hazardous areas and it provides many benefits.

Intrinsically safe technology prevents explosions by ensuring that the energy transferred to hazardous areas is well below the energy required to initiate an explosion. Intrinsically safe systems enable equipment to be used without risk of igniting any flammable gas, dust or fibres that may be present in hazardous areas.

A free white paper from Mettler Toledo, Intrinsically Safe Solutions - Accurate Weighing  for Hazardous Areas, describes the principles of the intrinsic safety protection method, highlights the benefits and provides examples of possible weighing configurations in hazardous areas.
